Both at home and abroad to the removal of suspended substance, generally adopt flocculent precipitation at present.Water-quality guideline situation according to sewer adopts this method, and is equipped with the indicator of suspended solids that ultra-filtration system can make sewer and reaches the circulating cooling make-up water requirement.The desalination technology of widespread use both at home and abroad mainly contains at present: ion exchange method, reverse osmosis method and electroosmose process.
According to the Wastewater Form Circulating Cooling Water characteristics, petroleum chemical enterprise adopts more advanced two embrane methods (CMF+RO) art breading reuse circulating cooling system sewerage mostly.Eraring power plant, Chinese Tianjin Economic Technology Development Zone Sewage Disposal Facatory in California, USA 21 century water factory, water treatment plant, Western United States basin, Australia all adopt two embrane method (CMF+RO) regeneration municipal effluents and trade effluent.Two embrane methods (CMF+RO) purification of waste water reuse technology utilizes microfiltration membrane (CMF) to realize that except the core technology of turbidity, reverse osmosis (RO) desalination about 80% purification of waste water is back to use circulating water system, and about 20% concentrated waste water send waste disposal plant to process.
Some electric power plant circulating water sewer adopts respectively the sodium hydroxide coagulation clarification to process and the lime coagulation clarifying treatment, realizes the maximum utilization of water resources in the factory,
Some electric power plant circulating water draws and adopts immersion ultrafiltration, reverse osmosis process to process by immersion ultrafiltration and the contrast of pressure type ultra-filtration technique scheme, and it is pre-to satisfy boiler feedwater, the water quality requirement of desalination.
Because traditional Circulating water effluent intake design is certain some position of high 10cm at the bottom of circulating water pool, along with the Circulating Water Field cycle of operation prolongs, biological clay is more long-pending thicker at the bottom of being deposited on circulating water pool, live in various mushrooms under the foundry loam because the obstruction of foundry loam layer, the various mushrooms of living under the foundry loam are difficult to be killed Fast-propagation by sterilant, the foundry loam corruption is risen, in circulating water system, form vicious cycle, cause turbidity of circulating water, biological clay content higher, have a strong impact on water quality.
In addition with application of membrane when processing And Reuse Wastewater From Circulating Water, although can improve its product water quality, some in addition can be used as feedwater and use, but because the price of film is high, the cost of disposing of sewage increases, and adopts coagulation clarification to process, and existing again increases recirculated water dielectric medium risk.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of biological clay deposition at the bottom of the circulating water pool that prevents is provided, improve the circulating water pool blowdown apparatus of fungicide effect, reduction circulating cooling make-up water amount, have short, flat, fast characteristics, solve circulating water pool biological clay deposition problems, reduce the Circulating water effluent amount, improve the recirculated water cycles of concentration, guarantee the Circulating Water Field long-time running.
A kind of circulating water pool blowdown apparatus, comprise circulating water pool, the inherent water surface in described pond is to have main intake pipe, described main intake pipe is provided with a plurality of suction pipes, the water-in of described suction pipe is towards described basin bottom, the water outlet of described suction pipe is connected with described main intake pipe, described main intake pipe is connected with in-line pump by hydraulic pipe, the water outlet of described in-line pump is connected with the water-in of the husky filter of shallow-layer system, the water outlet that the husky filter of described shallow-layer system connects connects return line, and described return line is connected with described circulating water pool.
In the utility model, described main intake pipe is provided with a plurality of dendritic branches intake pipe, also is provided with a plurality of suction pipes on the described branch intake pipe.
In the utility model, the water-in of described suction pipe is from described circulating water pool bottom 0.5cm～1cm.
In the utility model, be connected with filling pipe on the described hydraulic pipe, described filling pipe water source returns tower water with circulation and is connected.
In the utility model, be connected with blow-off pipe on the described hydraulic pipe, the inherent main intake pipe of described hydraulic pipe is to being equipped with the turbidity on-line analyser between the end-of-the-pipe, the control end of described turbidity on-line analyser be installed in described blow-off pipe on the solenoid control end be connected the control end of in-line pump and be connected.
In the utility model, described hydraulic pipe is provided with the blow-down pipe that an end is communicated with described hydraulic pipe, the other end of described blow-down pipe and air communication, and on the described blow-down pipe valve is installed.
In the utility model, described suction pipe be import large, go out young shape.
In the utility model, be equipped with valve on described hydraulic pipe and the described water inlet pipe.
Adopt such scheme, the utlity model has following advantage:
1, this device increases new intake pipe on the basis of original blowdown apparatus, and less investment is simple to operate, reliable;
2, by the turbidity on-line analyser, strengthen the monitoring dynamics, when turbidity can not be processed during greater than set(ting)value, just sewage is discharged, reduce blindly blowdown;
